acpi: thermal: display forced passive trip points in proc
Users can force a passive trip point for a thermal zone that does not have _PSV defined in ACPI by setting the passive attribute in sysfs. It's useful to display such trip points in /proc/acpi/thermal_zone. .../TZ1/cooling_mode:<setting not supported> .../TZ1/polling_frequency:polling frequency: 10 seconds .../TZ1/state:state: ok .../TZ1/temperature:temperature: 53 C .../TZ1/trip_points:critical (S5): 110 C .../TZ1/trip_points:passive (forced): 95 C And if not set (passive is 0): .../TZ1/trip_points:passive (forced):<not set> Signed-off-by: Frans Pop <elendil@planet.nl> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Len Brown <len.brown@intel.com>
